My post world cup very early predictions for Euro 2020
France - Winners
Most of their key squad should be around in 2 years. The likes of Mbappe, Pogba, Griezmann, Kante, Umtiti et al. have cemented their status in the XI. A key position up for grabs will be the No. 9 as Giroud will likely retire from the national team after having an average world cup. Lloris should still be good for another run but Areola could see more playing time in 2020. Matuidi would also be at the cross roads for the national team. It'll be interesting to see how the players that didn't make the WC will play over the next 2 seasons. Martial, Bakayoko, Rabiot, Coman and Zouma are some names to keep an eye out for.
Belgium - Runner-ups
The Golden Generation of Belgium is approaching what could be seen as their last realistic chance of lifting silverware. The likes of Hazard, KDB, Lukaku and Mertens would be approaching their late 20'/early 30's by WC 2022, hardly ideal for a game that is increasingly more athletically competitive. Euro 2020 should see thier key players reaching the peak of their playing career. There will be a question of how to plug their defensive midfield as Witsel, Fellaini and Dembele may not have the legs needed for the engine room come 2020.
Italy - Semi-finalist
Italy is at an interesting juncture as it will need total revamping practically at every position. Here's the break: Italy has a crop of players that should peak come 2020. A midfield of Veratti and Jorgihno gives Italy to solid box to box players, and Gagliardini would provide defensive cover. Rugani and Romangoli look set to set up shop at the center of backline. Going forward there's a good mix of proven goal scorers in Immobile, Insigne and Balotelli as well as younger talent in Cuttrone and Bernadeschi. Donnarumma should be the first choice between the sticks. There is a question, however, about Italy out wide. There are no clear favorites for either the left or right fullback position and outside of El Sharawy, there aren't too many inventive Italian wingers at the moment.
Germany - Semi-finalist
Low and the Germans will want to forget the mess that was the 2018 World Cup. However, their disappointing display was not all too surprising. The German side was aging and had not done a good job of intergrating a lot of the promising young talent that won them the 2017 Confederations Cup and 2017 U-23 Euros. 2020 will be stage to right their wrongs. The likes of Sane, Werner, Goretzka and Kimkich should be no brainers for the first 11. Members of the old guard that could possibly retain their spots include Kroos, Reus and Draxler. Rudiger should provide ample replacement for Boateng who, after this last WC, should see his retirement with the national squad. Neuer should have another go with the squad but Ter Stegen could fill in as the first choice keeper should things go awry. What will be interesting to see is how Low adapts this German national side that will be feature many new faces into the winning machine of old.
